Application filed April 23,

This invention relates to motion picture cameras and more particularly to the adaptation of such cameras for use with special film magazines which cooperate therewith.

The objects of my invention are to provide that will have two light sealed openings so located that when the magazine is in either position in the camera oneopenmg Wlll be available for .feed or take-up purposes; and

to provide a structure that will-be easy to operate, and inexpensive to manufacture.

ig. 12 is a section on line 12-12 of a rotatable core section on line 11-11 of a compact box form of the neral type described in my pending application Serial No. 378,616 filed May 3, 1920, \which matured into Patent 1,572,252 granted Feb. 9, 1926, and comprisesia casing 1 having a film compartment 2 in w ich are the film magazines 3 from one of wh oh the film 4 passes over a sprocket wheel 5 to a suitable gate 6 and then back. over the arcuate, concentric with the opening 33, ex-- 1924. Serial No. 708,545.

sprocket to the second ma azine. It is held in place on the sprocket y presser de- 1 vices 7. The compartment has an upper wall 8, a rear-wall 9,.lower wall 10 and bottom 11'. Shafts 12 with latches .13 are provided for the magazines.

Secured on the bottom of the compartment is an adapter plate 14 having' apertures 15 fitting over shafts 12 and small apertures 16' for securing means such as screws (not-shown). At appropriate points on this plate are lugs 17, 18 and 19' bent -up perpendicularly tothe plate, and other supporting lugs 20, 21, 22 and 23 bent slightly out of the plane of the plate and parallel thereto.

A magazine 3 comprises two similarly shaped telescoping members 24 and 25. The I inner member 24 is formed from two sheet metal elements 26 and 27. The element 26 has a bottom 34- with an opening 33 surrounded by an inwardly extending rim 50, an outer edge bead '28 and a peripheral flange 29. The periphery of this element is cept for an extension 30, the sides 31 of which are straight, .tangential to the are, perpendicular to each other and joined by "the rounded corner 32. The element 27 fits within element 26' and has a bottom 35 with an aperture 36 larger than aperture 33 and I coaxial therewith, and ribs 37 radial to this aperture. It has a peripheral flange 38 fitting closely within flange 29. At the end of the" extension, the top of this flange is continued and bent over to form a bracket '39, between which and bottom 35 is mounted a roller 40 on an axis 41 Elements 26 and 27 are held in place functionally so that 27 can be removed and the tunnel cleaned.

As is obvious, the magazine is oval orpear shaped. In the flange 29, symmetrically laced at the'broad end, are apertures 42; art of the metal at the edges of the apertures is turned back to form strengthen ing beads 43. The flanges 38; from points 45 opposite the straight portions 31 v to points beyond the aperture 42 are bent to.

form tunnels 44, these being open ended.- They are struck up further at theinmedian portions 46 than at their" borders '47 as shown in Fig. 9, so that thefilm 4 contacts 2 them only at its edges. Near the points 45 7 there are formed protuberances 48 in the flanges 38 to assist in directing the film be.-'

slots 77, so thatit rests in the channel 78 tween the roller 40 and a point 45. It is firmly clasped and positioned at its edges by obvious that film 4 from a roll within the magazine may pass over the roller 40 in either direction to the corresponding tunnel 44 and aperture 42 to the outside of the casing, and that the tunnel forms a light trap.

The outer or cover member 25 of the magazine fits closely over the inner member 24 and, like it, comprises outer and inner elements 51 and 52. The outerelement 51 has an oval bottom 53 with a peripheral bead 54 and flanges 55 and an aperture 56 surrounded by the inwardly extending rim 57. From flange 55 are cut. apertures 58 which register with apertures 42 when the magazine is closed and cut-out portion 59 to facilitate removal of the cover member 25. There is formed on flange 55 a struck out protuberance 60, the function of which will be described later.

The inner element 52 has no flange and consists merely of a plate which-is circular except for a straight edge 61 opposite the extended part of the magazine, thus affording space for the positioning of bracket 39 when the magazine is closed.- T he element 52 has an aperture 62 surrounding riin. 57

and radial ribs 63. It is attached to the element 51 byany desired means, as by spot welding at 64. Y

There is used in the magazine a core 65 showmin Figs. 4 to 6. This has a cylindrical sheet metal hub element 66 on the ends of which are slipped two flange eleinents 67 which aresimilar, except that one has a square central hole 68 and the other a round hole 69. Each has a flange portion 70 tightly surrounding hub 65 and is then bent out at 71 and back at 72 to form an annular channel 73. It is then again bent out at 74 and in to form flanges 75. The edges 76 of the flange elements 67 are spacedapart so that the parts form the supports for the edges only of the film. There are formed slots 77 in the flanges 75. The end of the film 4 isslipped into the formed under flange 75 and is then bent back as the film is wound on the core, being securely held thereby.

The operation and use of the apparatus will now be described; It is intended that the magazine will be loaded at the factory, the film 4 being wound on the core 65, which is enclosed within the magazine. The rims 50"and 56 will enter the channels 72 of the core and constitute light traps. The outer end of the film will extend around roller 40 zine is positioned in the camera, its bottom resting on the lugs 20 and 21 andbeing direction. The film magazine in eac lugs 17 and 18. The lug 60 will rest a ainst wall 9. The magazine is purposely so dimensioned that there will be a slight space below wall 8, making insertion easier.-

Since the film will be so wound that it will unroll in a clockwise direction, themagazine will be firmly positioned.

-The film is drawn out and threaded past the sprocket and gate. Another empty magazine is provided and opened and the member "24 thereof positioned, its bottom resting on lugs 22 and 23 and its edges beingengaged by lug 19. The core is positioned with the square hole inside to engage a correspondingly shaped shaft, whereby it is driven. The end of the film is passed through the hole 29 which will be situated nearer the sprocket, tunnel 44, around roller 40 and secured to the core. The cover member 25' of the ma azine is slipped over member 24 with its lug 60 engaging the lower wall 10.

An easier method of loading is to secure the end Ofv the film in the second magazine before the latter is positioned in take-up position and, after positioning both magazines, form a slack loop which is positioned about the sprocket and gate in the manner described in my above-mentioned application.

- The ribs 37 and 63 hold the edges of the film roll in alignment with very little -f1'ic-' tion, so that it turns readily. When the a magazine is in the u er or su l osition the film will be fed diit of onii tiiniiel, and when it is in the lower or take-up position, it will be fed out through the other tunnel, passing around the roller in. the opposite 1 051- tion has the same side outermost, but the position of its extension is different, bringing the proper aperture adjacent the sprocket wheel of the camera. a

It is obvious that numerous embodiments of my invention are possible and I contemplate all such modifications and equivalents as fall within the scope of the appended claims. i a I Having thus described my .invention what I claim as new, and desire to obtain by Letters Patent is: y

and having re ister film magazines having symmetrical extensions and each having symmetricallyarranged film passages, whereby the magazines may be positioned with the extension in either of the two corners and in either position a film passage will be adjacent the film feeding means.

9. In combination with a motion picture camera having means for positioning a film magazine in supply position and means for positioning another similar film magazine, in take-up position, and having film feeding means for withdrawing film from a magazine in the first position and feeding it to a magazine in the second position, film magazines adapted to fit such positioning means and having a pluralit of light trapped film passages so positione that one of them will be in operative position with respect to the film feeding means in each position of the magazine, the film magazine being so shaped that it can be positioned only in proper nositionin each position.
